a corporation of New Application. February 8, 1940, SerialNo. $117,914-v 3- Claims. 129-24) This invention relates. to. loose leaf binders and more particularly to; a loose leaf binder. in the. form of a record bookin. which the pages or leaves are added from. time to time in consecutive. order until. the binder. is filled. For example, binders. of. this. type. are employed to receive photostatic copies of recorded instruments, the copies being added, atv the back of the binder consecutively according to filing date. The invention; has. asv an. object. a. loose leaf binder of. the type referred to. embodying aconstruction which, while particularly simplev and economical to manufacture, rigid and. durable in use. and is neatand attractive in appearance.

The invention. consists in the novel features and. in the combinationsand. constructions her-e inafter set forth and. claimed.

In describing. this invention, reference is had to. theaccompanying drawingsin whichlike characters. designate corresponding. parts in all the views..

Figure 1 is a perspective view of a binder embodying our invention- Figure 2. is. a. rear perspective. view of. the leaf impaling post. supporting member.

Figure 3- is a cross sectional view of the binder shown in Figure 1 in closed position.

Figure 4 is a transverse, sectional View of the binder with the rear cover in open position and the back member detached from the leaf impaling posts.

Figure 5 in an enlarged detail View illustrating the interlock between the pintle rod for detachably securing the posts to the post supporting member.

Figure 6 is a view, similar to Figure 5, illustrating the pintle rod in unlocked position.

The binder consists of a trough-shaped back member I0 formed of sheet metal with spaced apart hinge eyes along each edge to receive pintle rods II. The front and back covers I2, l3 are also provided with hinge eyes I4 to receive the pintle rods I I, whereby the covers are hinged to the back member III in the conventional manner.

The leaf impaling unit of the binder consists of a channel-shaped member having a bottom wall I5 and side walls I6, H. The bottom wall I5 is formed at each end with rearwardly extending projections I8 forming closures for the end of the trough-shaped back member I0. The channel member is secured to the back member I0 by a plurality of straps extending transversely of the bottom wall I5 and being formed at each end with a hinge eye 2|. The straps 20 are secured to the bottom. wall I5 of the channel: member by tubular projections. 2-12 extruded from the bottom wall I5 and spun or. swedged over as: at 23; Theeyes- 2| are arranged in alinementv with the eyes I4 of the covers. I2;

I3, anclthe eyeson the edges of the back member l6, whereby the channel. member is securedto the back memberby the pintle rods II. Y

The leaves' are arranged on the posts 2-4,. like ends of which arepermanently secured tov the. side I5 of the channel member. by a: pintle rod 25- extending through the ends of the posts and hinge eyes; 2.5 formed in spaced relation. along the edge of-.the side wall IS. The oppositeends of the. posts,. adjacent the back cover 13, are. detachably secured to "the opposite side ll of the channel member. by a -.pintle rod- 21- extending through the opposite ends of the posts and the; hinge eyes 28formedalongtheedge of; the sideI I. The pintle rod; 21 is.- removable to permit the ends-ofthe posts to be'detached from the side;- I1 of the channel member in; order to permit the back member I0 to! be swungoutwardly; as l in Figure 4:, for: the insertionqofv leaves on the posts 24. One end of the rod. 21 isbent to form a loopv 29 which serves as a convenient handle. for; manipulating, the rod. Theside wall I] isprovided with a spring clip 30 arranged to be engaged by the inner end of the loop 29 when the rod 21 is in post engaging position. The clip 30 serves to retain the rod from rotation and from outward axial movement. The rod 21 is removed from the eyes 28 to permit release of the posts 24 by shifting the loop 29 inwardly to move the inner end thereof out of engagement with the clip 30, whereupon the rod may be rotated to move the loop out of alinement with the clip. The rod may be then pulled outwardly its full length to release the ends of the posts 24 from the sides I! of the channel member.

When the additional pages have been inserted on the posts 24 and the free ends of the posts have been moved into the spaces between the eyes 28, the rod is pushed inwardly through the eyes 28 and the apertures in the ends of the posts and the rod then rotated in a clockwise direction Figure 1 to bring the loop in parallel relation to the side member IT. A slight outward movement then moves the inner end of the loop 29 into engagement with the clip 30.

It will be observed that the binder consists of a minimum number of parts which are particularly economical to manufacture and are so constructed and arranged as to form a binder of minimum weight and maximum durability.

What we claim is:

1. A loose leaf binder comprising a troughshaped back member formed with hinge eyes along each edge thereof, a cover hinged to each edge of the back member on a pintle rod extending through corresponding ones of said hinge eyes, a channel-shaped member extending lengthwise of said back member with the sides of the channel member extending inwardly from the back member, a plurality of straps secured to the bottom of said channel member and extending transversely thereof and being formed at their ends with hinge eyes engaging the pintle rods of said covers, each side of said channel member being formed with spaced apart hinge eyes, a plurality of leaf impaling posts secured at like ends to the hinge eyes on one side of said channel member, a removable pintle rod extending through the hinge eyes on the opposite side of said channel member and being operable to detachably secure the opposite ends of the posts to said opposite side of said channel member, said last mentioned pintle rod being formed at one end with a loop and said other side of the channel member having a projection, said loop being movable into engagement with said projection when said rod is in post engaging position, and said projection being operable to detachably interlock said rod to said other side of the channel member.

2. A loose leaf binder comprising a troughshaped back member formed with hinge eyes along each edge thereof, a cover hinged to each edge of the back member on a pintle rod extending through corresponding ones of said hinge eyes, a channel-shaped member extending lengthwise of said back member with the sides of the channel member extending inwardly from the back member, a plurality of straps secured to the bottom of said channel member and extending transversely thereof and being formed at their ends with hinge eyes engaging the pintle rods of said covers, each side of said channel member being formed with spaced apart hinge eyes, a plurality of leaf impaling posts secured at like ends to the hinge eyes on one side of said channel member, a removable pintle rod extending through the hinge eyes on the opposite side of said channel member and being operable to detachably secure the opposite ends of the posts to said opposite side of said channel member, said last-mentioned pintle rod being formed at one end. with a loop, said other side of the channel member being formed with a clip, the inner end of said loop being movable into alinement with said clip upon rotation of said rod and being movable into engagement with the clip upon outward axial movement of the rod, said clip being operable to detachably interlock said loop and rod to said other side of the channel member.

3. A loose leaf binder comprising a troughshaped back member formed with hinge eyes along each edge thereof, a cover hinged to each edge of the back member on a pintle rod extending through corresponding ones of said hinge eyes, a channel-shaped member extending lengthwise of said back member with the sides of the channel member extending inwardly from the back member, the bottom of said channel member being provided with laterally extending eyes engaged by said pintle rods, each side of said channel member being formed with spaced apart hinge eyes, a plurality of leaf impaling posts secured at like ends to the hinge eyes on one side of said channel member, a removable pintle rod extending through the hinge eyes on the opposite side of the channel member and being operable to detachably secure the opposite ends of the posts to said opposite side of said channel member, said last mentioned pintle rod being formed with a laterally extending projection adjacent one end thereof, means carried by the opposite side of the channel member and cooperable upon engagement therewith by said projection to detachably interlock said pintle rod to said opposite side of the channel member, said projection being movable into and out of engagement with said means upon combined axial and rotatable movement of said pintle rod.
